Ballistic missile defense (BMD) politics present an interesting evolution in how the USA, especially Congress, has come to think about BMD both as operational reality and as a symbolic policy. The argument here is that BMD's operational reality is increasingly overshadowed by its symbolic aspects. Such a status arose from rapidly changing international and domestic politics. The end result is a situation in which BMD policy in a sense floats above the question of its actual combat effectiveness. Its primary mission in part is sustaining US capacity to remain a global power and support its allies. 相似文献

Islamist extremism as an ideology has seemingly spread in influence in the past few years. The violent Islamist threat may have a singular religious dogma, but that does not mean that it will interact in the same fashion within the various cultures it infests. The Sub-Saharan region is one general context where Islamist extremism is both vividly active and misunderstood. Africa's reaction to: Arabization; the adjustment to post-colonial rule; the perception of secular government institutions; the extent of cultural and religious pluralism; and the local character of Muslim leadership and institutions are all very different from that of the Middle East. Scores of terrorism analysts and even Arab populations only too familiar with the Middle East context superimpose Middle East threats over the Sub-Saharan African cultural landscape. Instead of generalizing the Islamist threats, it might be better to ask why it is that violent Islamist groups have traditionally been challenged to expand their influence in Muslim Sub-Saharan Africa. The underestimated Islamist is using ignorance to its advantage, recruiting through channels unnoticed by its Arab counterparts while creatively catering its message by region. 相似文献

This Critical Comment seeks to situate the United Nations Convention on the Law of the Sea (UNCLOS) within the context of South China Sea (SCS) dispute. Bearing in mind that maritime actions of the main disputants – China, Vietnam, and the Philippines – increasingly “securitise” these long-standing disputes and vice versa, the study examines the concept of a maritime “regime complex.” Whereas efforts have being made to examine UNCLOS and indeed the dispute within the framework of a maritime “regime complex,” the key finding shows that the increased “securitisation” of the disputes makes it difficult to envisage effective engagement of UNCLOS as a resolution mechanism. It will also reveal that China's firmly established expansionist agenda in the SCS region is indicative of Beijing's susceptibility to compromise a diplomatic solution to these long-standing disputes. These discoveries are structured around the knowledge that the spatial relation of the SCS critically espouses not only its geo-strategic significance in terms of natural resources endowment, but also the enduring maritime disputes within the region. 相似文献

I explore the relationship between superpower arms transfers and the Arab‐Israeli rivalry. My empirical analysis suggests that Soviet arms transfers to the Middle East, more than American transfers, have exacerbated interstate rivalry in the region. It also suggests that Soviet arms transfers, again more than American transfers, have encouraged compensatory arming by the other superpower. These conclusions derive from the results of cross‐correlation analysis, Granger‐causality tests, and variance decompositions, and are quite robust. While my findings paint a rather unflattering portrait of the effects of superpower involvement in the region, they do constitute grounds for optimism in light of current developments. 相似文献

This survey article deals with defence spending in West Germany from 1960 on, and the resulting manpower levels and major weapons of the Federal Armed forces, focusing on macro‐economic aspects. Statistics compiled from a variety of published and unpublished sources are presented in 16 tables. An econometric defence‐spending function is derived for the period. For comparison, the equivalent data of East Germany from the last years is also presented. The small set of developments in the next few years that can be predicted firmly are discussed. 相似文献

The issue that this paper tackles is the assessment of the relative security benefits that Cyprus and Greece derive in the context of their cooperation on defence matters. This form of cooperation, known as the ‘Integrated Defence Space Doctrine’, aims at defending their interests in the Aegean Sea and the broader East Mediterranean theatre. The paper relies heavily on earlier research on this topic, which deals with the Greek–Cypriot alliance facing an arms race against Turkey, and uses a coefficient especially designed to assess the optimal levels of security and the associated defence expenditure of the two allies. A comparison of the relative security coefficient values for the two allies suggests that the security benefit that Greece derives thanks to its alliance with Cyprus exceeds the corresponding Cypriot benefit by far. Given the importance assigned to human resources by this index, in conjunction with the demographic problems of Greece, this conclusion justifies the recent Greek defence policy revision, emphasizing quality, capital equipment and flexibility of forces. This revision aims at satisfying the security requirements of the alliance and the increasing demands of an arms race against Turkey. 相似文献

An interactive economic model of military spending is proposed. It is quantified on the basis of cross section data for East Asia. Projections of military spending to the end of the decade suggest that the growth of military spending in the region will decline slightly in the current decade. East Asian military spending can, however, be greatly influenced by the path of Chinese and US military efforts. An expansion of military spending by China could cause neighboring countries to greatly increase their military expenditures. 相似文献

Guinea-Bissau's transition toward democracy has been violent and disruptive. Despite holding elections and attempts to promote economic and social development, the latest government, under President Yala, is not equipped to bring stability or even a more democratic state. A politicised military, inexperienced opposition and corrupt government officials have contributed to the current poverty and instability. Although unlikely to be deposed by the fragmented opposition, Yala is not secure within his own party and is likely to use his position to weaken his opponents. As a Catholic, Yala has been careful to avoid religious conflict by reassuring Muslim citizens that they will not be marginalised. The economy is precarious and poverty has not been addressed. Guinea-Bissau is dependent on foreign donors for its financial needs. Guinea-Bissau has begun military operations against rebels opposing the Senegalese government and the battles seem likely to continue to cause regional instability. Without external intervention political and economic development looks remote. 相似文献

International judicial norms developed slowly during the Cold War but have recently begun to draw on the experiences of the Criminal Tribunal in the former Yugoslavia and Rwanda. These ad hoc bodies had to respond quickly to emergency situations by combining different international approaches to justice and prosecution. The Special Court for Sierra Leone is the latest of these experiments. Despite having had more time for reflective discussion and negotiation, the Special Court faces the same challenge and constraint: the parameters of time and resources are set by political imperatives. The International Criminal Court goes some way to addressing the problems of funding, good judicial appointments and contrasting legal systems, the details of future trials will not be easy. Ad hoc tribunals will probably still have a role to play in cases where the ICC cannot intervene. 相似文献

North Korea has been one of the world's most active suppliers of ballistic missile systems since the mid-1980s, but the nature of its missile export business has changed significantly during this period. Unclassified, publicly available data show that the great majority of known deliveries of complete missile systems from North Korea occurred before 1994. The subsequent fall-off took place a decade too early to be explained by the Proliferation Security Initiative of 2003. It can be explained by a combination of factors that have reduced demand. First, after selling production equipment for ballistic missiles to many states, especially in the Middle East, North Korea by the late 1990s had become primarily a supplier of missile parts and materials, not complete systems. Second, after Operation Desert Storm, some missile-buying states shifted their attention away from ballistic missiles in favor of manned aircraft, cruise missiles, and missile defense systems supplied by Western powers. Third, some states experienced pressure from the United States to curtail their dealings with North Korea. During the last decade, having shed most of its previous customer base, North Korea has entered a phase of collaborative missile development with a smaller number of state partners, particularly Iran and Syria. Its known sales of complete missile systems are relatively small and infrequent. North Korea's time as missile supplier to the Middle East at large has ended, but there is a risk that regional states will turn to North Korea as a supplier of nuclear technology in the future. 相似文献
